Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, more particularly to a fixture for controlling the spacing of reinforcing steel bars and the thickness of the protective layer. BACKGROUND

[0002] In reinforced concrete construction, controlling the spacing of reinforcing steel bars is an important means for the concrete project to fully exert the tensile properties of the reinforcing steel bars. At present, the spacing of reinforcing steel bars is often controlled by measuring with a steel ruler or by the experience of workers, and rectification is carried out through post-construction acceptance. This method is heavily influenced by personal subjective opinions and is prone to deviation. The thickness of the protective layer of reinforcing steel bars is generally controlled by making cement blocks of the same thickness as the protective layer on site or by purchasing prefabricated blocks, which are placed under the reinforcing steel bars during the binding of the reinforcing steel bars, or by using short reinforcing steel bars to control the thickness of the protective layer. Although this method has some effect, it also has many problems. For example, the cement blocks are often crushed or difficult to control in place during subsequent construction, making it impossible to effectively control the protective layer of the reinforcing steel bars during concrete construction. Using short reinforcing steel bars to control the thickness of the protective layer is economically feasible, but the position of the reinforcing steel bars may change due to human or machine pressure during construction, affecting the accuracy of the thickness of the protective layer.

[0003] During the binding of reinforcing steel bars, there are many influencing factors. If one factor is uncontrollable, it can easily lead to uneven quality of the binding of reinforcing steel bars.

[0004] During engineering construction, the spacing of reinforcing steel bars is often controlled by measuring with a steel ruler, and the thickness of the protective layer is controlled by hanging and binding blocks. Workers often bind the reinforcing steel bars based on their own subjective experience for the sake of convenience, which can not meet the requirements of quality engineering. Moreover, if the spacing of the reinforcing steel bars does not meet the design requirements, it can affect the load-bearing properties of the concrete structure, possibly leading to uneven stress on the structure when it is under load, reducing the load-bearing capacity and stability of the structure. At the same time, insufficient thickness of the protective layer of reinforcing steel bars can make the reinforcing steel bars easily eroded by the external environment, such as the intrusion of corrosive media, causing corrosion of the reinforcing steel bars and affecting the durability and safety of the structure. On the contrary, if the thickness of the protective layer of reinforcing steel bars is too large, it can change the position of the reinforcing steel bars in the structure, causing changes in the stress situation of the structure and reducing the load-bearing capacity of the structure.

[0005] Therefore, it is necessary to propose a fixture for controlling the spacing of reinforcing steel bars and the thickness of the protective layer to solve the errors in the binding of reinforcing steel bars and the poor control of the outer protective layer of reinforcing steel bars in reinforced concrete construction, which is of great significance for improving the load-bearing capacity of concrete. SUMMARY

[0006] The utility model provides a fixture of controlling steel bar spacing and protective layer thickness to solve the technical problem of the big error of steel bar binding and the poor control of the outer protective layer of steel bar in prior art, which leads to the low quality of reinforced concrete engineering.

[0007] According to an aspect of the utility model, a fixture of controlling steel bar spacing and protective layer thickness is provided for being installed at the end face of a formwork for concrete pouring, the fixture comprises a plate body, the upper end face of the plate body is provided with open grooves arranged at intervals, the spacing between the open grooves is the spacing between adjacent steel bars, and a limiting groove is arranged at the middle of the bottom of the open groove.

[0008] On the basis of the above-mentioned scheme, the middle of the end face of the plate body away from the open groove extends outward to form a mounting edge.

[0009] On the basis of the above-mentioned scheme, a mounting hole is arranged on the mounting edge, and the plate body is fixed to the end face of the formwork through the mounting hole.

[0010] On the basis of the above-mentioned scheme, the mounting hole is in the shape of a cross, comprising a height adjusting hole along the length direction of the open groove and a width adjusting hole along the width direction of the open groove, and the width adjusting hole is in communication with the height adjusting hole.

[0011] The utility model discloses a fixture of controlling steel bar spacing and protective layer thickness, which is installed at the end face of a formwork, and the open groove can be used to accurately limit the spacing between adjacent steel bars. In combination with the limiting groove at the bottom of the open groove, the spacing between the formwork and the steel bars can be limited to prevent the formwork from approaching the steel bars, thereby ensuring the thickness of the protective layer. The problems of relying on the experience and working attitude of workers in steel bar binding operation are completely solved, and the steel bar binding operation is more convenient and reliable, thereby improving the quality of steel bar binding operation.
